Hi!
Zitat von Madshrimps:
"For the GPU core voltage mod we must search for the Primarion PX3540 PWM IC. The resistor marked in blue is the one you need to shade with your B2 pencil. Strike it a few times and measure how the resistance changed, you can check resistance by holding the red wire of your multimeter to the red point and the black wire of your multimeter to the pink point.
The stock resistance measures around 35 Ohm, this is very low and this will make it very hard to pencil mod the GPU core voltage, we recommend doing the soldered modification. For the solder mod we used a 1kOhm adjustable resistor (often called VR) and soldered it between the red and pink point. This changed our stock voltage from 1.3V to 1.33V. To further increase voltage we must lower the resistance of the variable resistor, before you power on your system always make sure that your VR is set to highest value. For 1,4V we adjusted the stock resistance of 35 Ohm to 29 Ohm."
Ob dies der Wahrheit entspricht, konnte ich bis jetzt nicht nach vollziehen.
Auf anderen Seiten habe ich aber schon gelesen, dass aufgrund des niedrigen Widerstandes von 30 bis 40 Ohm, ein Pencil-Mod nur schwer zu realisieren ist.
Gruß Tom

. Zocke ja in 1680 @ High (was geht).
